Abstract

To reduce the material in a transformer core and winding assembly, the edges of the core winding legs are relieved so as to achieve improved conformity with the inside corners of the coils disposed thereabout. More intimate spacing of the coils relative to the legs is therefore accommodated with consequent material savings in both the core and the winding coils. Methods for relieving the leg edges by bevelling and notching are disclosed.
